The vehicle to be positioned can exchange UWB packets with the positioning aid devices by means of the UWB electronic tag to obtain the positions of the positioning aid devices (S402). The vehicle to be positioned can determine the distance between itself and each positioning aid device according to the time difference between sending and receiving UWB packets, and the vehicle to be positioned can determine its own position according to the distance between itself and each positioning aid device in combination with the positions of the positioning aid devices (S406).
